Specification of Letters Patent.

Patented Dee. 31, 1918.

Application led September 29, 1917. Serial No. 194,000.

To all whom t may concern:

Be it known that I,.Mrs. Slm S. H AY'DON, a citizen of the United States, residing at Harrodsburg, in the county of Mercer and State of Kentucky, have invented new and useful Improvements in Ventilating-Doors, of which the following is a specification.

This invention relates to Ventilating doors especially adapted to be used upon automobile machines and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a door of the character stated which includes a hollow upper portion open at its upper and lower edges and in which an imperforate panel is slidably mounted. A foraminous material is secured to the inner side ofthe said door section and extends from the lower edge thereof to the sill of the door frame. A strap is attached to the said panel and may be used for raising or lowering the same. The said panel is located beyond the outer surface ot the said foraminous material and may be lowered over the same whereby the door is closed from its upper edge to the sill of its frame. When the panel is raised by using.r the strap. the toraminous material is uncovered and hence air may pass through the same into the lower portion of the body of the vehicle and the heated air may pass out of the bodyY above the upper edge of the door.

ln the accompanying drawing:

Figure l is a side elevation of the door.

Fig. 2 is a transverse sectional view of the saine.

liig. 3 is a perspective view in the door structure.

'l'be section 1 which is hollow, is open at its upper and lower edges and is hinged in the frame of the body of the machine ina usual manner and which may be provided with any suitable pattern of latch or catch device. The section 1 is open from its upper to its lower edge and is closed vertical edges: therefore the said section includes an inner and outer side. A sheet of foraminous material 2 is attached at its upper edge to the lower portion of the inner side of the door section and may extend to the sill of the door frame when the door is in a closed position in the frame. The said of a panel used material 2 is preferably woven wire although it may be formed from perforated .sheet metal.

A panel 3 is slidnblymountedin the seealong itsl tion l between the inner and outer sides thereof and the said panel is preferably of metal and is imperforate. The panel 3 when in a lowered position with relation to the section 1 closes over the outer surface of thesheet 2 and consequently prevents the passage of air through the interstices or openings of the said sheet. A strap 4 of leather or other suitable flexible material is attached to the upper portion of the panel 3 and the strap is rovided with perforations 5, any one of whlch may be engaged over a, knob 6 which is mounted at the upper inner portion of the section 1.

When the panel 3 is moved to an elevated position in the section 1 and secured at such position by passing one of the perforations 5 over the knob 6 the sheet 2 is uncovered and consequently cool air from the exterior of I the body of the machine ma pass through the interstices or openings oty the said sheet and enter the low'er portion of the body of the vehicle. At the same time the heated air from the interior of the body of the vehicle ma escape therefrom over the upper edge o the section 1. By such an arrangement the body of the vehicle is kept free from the heated air or radiation from the `engine and is rendered comfortable while the engine is in operation.

From the foregoing description taken in i conjunction with the accompanying drawing, it will be seen that a ventilating door of simple and durable structure is provided and that the same may be conveniently used upon the body of an automobile for keeping the same in a cool and comfortable condition while the engine is in operation.

Having described the invention vwhat is claimed is:- t v 1. A Ventilating door comprising a body provided at its lower portion with an opening and having inner and outer side panels located above the opening, a sheet of foruminous material attached to the bodfv and stretched over the opening, a movable panel slidably mounted in the body and movable from a position over the sheet of foraminous material and in the opening of the body to a position between the side panels of the body, und means associated with said panel whereby the lattermay be elevated.

2. yA Ventilating door comprising a body provided at its lower portion with an opening and havingr inner and outer side panels located above the opening, a movable panel Y slidably mountedin the body and movable -to the body and stretched across the-opend from a position in the opening in the body to' ging, a movable panel slidably mounted rel- 1G a position between the side panels of the gjtively to the body and normally disposed body, and means connected with said panel giacross the opening to close the latter, and for moving the same out of the openin A"'-meams 4connected with ,said panel whereby 3.
